A gas tube doesn't get much attention until it stops doing its job, and this one from White Label Armory is built to just keep doing it. It's machined from seamless stainless steel tubing, sized specifically for rifle length gas systems, and made to route gas cleanly from the block back to the bolt carrier every single time you pull the trigger. If you're finishing a build, replacing a bent or worn tube, or just keeping a spare on the bench, this is a solid drop-in option for AR10 and AR15 platforms.
White Label Armory machines this rifle length gas tube from seamless stainless steel tubing rather than stamping or welding it together, which keeps the walls consistent and the gas flow predictable shot after shot. Stainless holds up well against the heat and carbon that come with a lot of trigger time, and since White Label Armory's parts come out of DRG Manufacturing's own CNC shop, you're getting a part that's actually held to a tight spec rather than mass produced and hoped for.
Rifle length gas systems were the original AR-15 setup, and they're still the go-to when you want the softest recoil impulse the platform can offer. That long dwell time means less pressure hitting the bolt carrier on the way back, which translates to gentler cycling and less wear on your parts over the long haul. This gas tube is built to that longer rifle length spec, so it's meant for barrels in the 18 to 20 inch range where a rifle length gas port placement makes sense, not for carbine or mid-length setups.
Swapping in a new gas tube is one of the more approachable jobs on an AR build, and this one fits right into that rifle length gas block and gas key setup without any modification needed. Keep in mind the roll pin that secures it to your gas block is sold separately, so grab one if you don't already have a spare on hand. Whether you're building fresh or fixing an old upper, this tube gets your gas system back in working order without overcomplicating things.
It's built to the standard rifle length spec, which runs right around 15.125 inches. That's the industry standard length used on the original AR-15 and M16 rifle length gas systems, so it should match up with other rifle length components without any surprises.
It's designed to fit standard rifle length gas systems on both AR15 and AR10 platforms. The gas tube diameter and length are shared across both platforms in rifle length configuration, so you shouldn't run into fitment issues either way.
No, the roll pin is sold as a separate item. If you don't have a spare gas tube roll pin on hand already, grab one before you start the install so you're not stuck mid build.
Rifle length gas systems are meant for barrels in the 18 to 20 inch range. Running it on a shorter barrel can throw off the gas port placement and lead to cycling issues, so stick with the longer barrels this system was designed around.
